These frame edge cover members 9 and I?! are flat plate-like members preferably made of wood and are arranged to cover the edges of the spool supporting frame members 3 and 4 at the open end portions of the slotted bearing portions 3e and '31, all as shown best in Figs. 1 and 2 of the drawings. These frame edge covermembers 9 and If! are arranged to be pivotally shifted away from the edge portions of the spool supporting frame members 3 and 4 when inserting one of the broadloom supporting spools 5, B, I or 8 into the spool supporting frame members 3 and 4.

The operating handle II is preferably circular in form, as shown inFigs. 4 and 6 of the drawings and this operating handle II is connected with the operating handle gear I2 by means of the shaft III), as shown best in Fig. 6 of the drawings. This shaft III) is revolubly mounted in the shank portion II a and this shank portion I Ia is provided with an enlarged end portion I I0 arranged to form an abutment at the outer side of the end frame member I, as indicated in Fig. l of the drawings.

The broadloom supporting spools 5, 6, I and 8 are substantially identical in form and therefore the broadloom supporting spool 5 will be described in detail. This broadloom supporting spool 5 is provided with a central tubular shaft member 5a, the opposite ends of which are arranged to engage the slotted bearing portions 36 or 3 of the spool supporting frame members 3 and 4.

Secured on the shaft member 5a near its one end is the spool operating gear I3. This spool operating gear I3 is substantially identical to the spool operating gears I4, I5 and I5 which are conventional spur gears. Positioned on the shaft member 50. adjacent the spool operating gear I3 is a disc-shaped end member 5b which is substantially identical in form to the disc-shaped member 50 positioned on and near the opposite end of the shaft 511, as shown best in Figs. 1 and 2 of the drawings. Secured on the inner sides of each of these disc-like members 5b and 5c are smaller disc-shaped plates 5d and 56. Secured on these smallerdisc-shaped plates 5d and 5e are slats 5 These slats 51 extend longitudinally and in parallel relation with the shaft 5a and are connected at their opposite ends with the disc-shaped members 511 and 56, as shown best in Figs. 1 and 2 of the drawings.

As shown in Figs. 1 and 2 of the drawings, the elevator shaft 20 is journalled at its opposite ends in the spool supporting frame members 3 and 4 at substantially the middle thereof and secured on this elevator shaft 20 adjacent the spool supporting frame member 3 is the elevator shaft operating gear 2|. This gear 2I is substantially the same diameter and form as the spool operating gears I3, I I, I5 and I5. Positioned in the spool supporting frame member 3 and the end frame member I is an opening 2m,

whichopening 2Ia is outwardly of the periphery of the elevator operating gear 2| and this opening 2 Ia is arranged to receive the operating handle gear I2 and is arranged to guide the same into mesh with the elevator operating gear 2|, as shown best in Fig. 4 of the drawings.

Pivotally mounted at opposite sides of the elevator operating gear ZI are the elevator latch members 25 and 25. These elevator latch members 24 and 25 are arranged to be pivotally shifted by the semi-circular in cross section latch portions I of the gear latch members It, all as shown best in Fig. 2 of the drawings. As shown in Fig. 4 of the drawings the gear latch members I 9 extend through the end frame member I and the spool supporting frame member 3 in cooperative relation with the elevator latch members 24 and 25 at opposite sides of the elevator operating gear ZI.

Secured on the elevator shaft 20 near its on- It will be here noted that the top member I1 is supported ,I at its opposite ends on the end frame members answer I and :32 and that the. end frame members I rand? 2' are interconnected at theirrlowerzi ends by means sof the bottom member" 1:31 The-elevator chains 2'2: and 23 extend upwardly: through the openings22a in. the top members llrand extend over the chain: supporting rollers. 26 and. hori zontallytherefrom .to' the pulleys 2 l andr28; as

shownbestin Figs; l, 2 and of the drawingsx The pulleys 21 and Nate substantially identical in formand' the supporting'mechanism' for each of these pulleys 21 and28 is substantially identicalni Therefore the pulley 28 together :with' its supporting mechanism will bedescribed in detaiL.

The pulley 2B is supported on. the ext-ending" endrof the tubular telescopic pulley supporting member29s as shown best in :Figs; 1, 2 and 5 stationary relation with the pulley supporting member 30, all as shown best in Figs. 1, 2 and 5 of the drawings.

As shown in Fig. 5 of the drawings; theelevator chainztextends upwardly from the elevator shaft 20 over the roller 26 and horizontally to the pulley 28 over the same and downwardlyinto connection with a roll A of broad-- loom material.

The operation of my broadloom exhibitor is substantially as follows: i I

When his desired to position brcadloom material upon one of the broadloom supporting spools 5, 6, 1 or 8,- one end of the piece of broadloom material is secured by tacks or otherwise on thelongitudinallydisposed slats thereof and the operating handle, together with the operating handle gear I2, is arranged in cooperative relation with: one of the holes la or lb whereby the operating handle gear 12 is in meshed relation with one of the spool operating gears I3, I4, E5 or' iii in connection with the broadloom supporting spool tobe operated. The operating handle I I-is then revolved and the operating handle gear l2 revolves the broadloom supporting spool in connection with the spool operating gear in mesh therewith. Thus the broadloom material is positioned on the broadloom supporting spool.

.When it is desired to change the position of aloaded broadloom supporting spool, as shown in Fig. 5 of the drawings, a strap A is positioned around each opposite end of the roll A of broadloom material and the elevator chains 22 and 23 are connected therewith. The operating handle II in connection with the operating handle gear I2 is arranged to operate the elevator operating gear 2! on the elevator shaft 2!! which is arranged to enroll the elevator chains 22 and 23 thereon.

It will be here noted that the slotted bearing portions 3e and 3] in the spool supporting frame members 3 and 4 are arranged to provide various spaced relation of the broadloom supporting spools 5, 6, l and 8 depending upon the diameter thereof when loaded with broadloom material. The gear latch members I9 are revolubly shifted into engagement with the spool operating gears I3, I 4, l5 and I6 and the semi-circular in cross section latch portions IEO of these gear latch The brackets 3i and 32 are each operating .gears,-. as" shown best in Fig; 3 of the' drawingsr When turned a quarter of a revolution, .these' semi-circular in cross section latch portions=l9c are disengaged fromthe gear'teeth of the spool operating gears l3, [4, land It, asdesired. The semi-circular in cross section latch portions We of the gear latch members l9 which engage the "elevator latch members 2e and 25' act as cams for pivoting the elevator latch members 24 and 25 into and out of engagement with the-elevator shaft operating gear 2| for holding the same in fixed position against revoluble operation in either direction, as desired:

As shown in Fig. 5 of the drawings, the'pule ley 28 supported on the pulley supporting member 29 may be extended outwardly into any position as desired depending upon the diameter of the roll:of broadloom material being sup-' ported on the elevator chains 22 and 23. When the roll A of broadloom material is elevated to. the proper elevated position relatively with the slotted bearing portions 3e and 3 in thespool supporting frame members 3 and 4, the pulley supporting member 29 may be telescoped into the pulley supporting members 39 shlftlng'the roll A of broadloom material toward the open portion of said slotted bearing portions 36 and 3] for positioning opposite ends of the broadloom supporting spool shaft in said slotted bearing portions 3e'or 3], as desired.
